CB7 accord distributor rotor

Hello all. I'm not sure if this site is still running but I'll try to post anyway. I need to get a new or 2nd hand distributor rotor. The number on my distributor is TD-31U but the rotor does not have a metal insert instead it has a series of ribs or castellations and the rotor just pushes on the shaft with a tight fit. There is a piece pressed onto the shaft which also has castlellations and corresponds to the rotor. I can't seem to find one of these anywhere.
